  • Page 11: Preliminary Operations

    Preliminary operations Removing the packaging and positioning the device On delivery, the packaging must be inspected to ensure that it is whole and that it has not been crushed or dented. Check in particular that neither of the two impact resistant devices on the packaging is red; if one of them is red; follow the instructions on the packaging.

  • Page 12: Installation Environment

    When being moved the cabinet should be handled with care; shocks or drops can damage it. Once in position, remove the packaging carefully in order not to scratch the device. The packaging should be removed as follows: Cut the bands Slide away the carton from above.

  • Page 13: Cooling Of The Premises

    Cooling of the premises The recommended operating temperature for the lifetime of the Frequency Converter (FC) and of the batteries is between 20 and 25°C. The lifespan of the battery depends on the operating temperature; with an operating temperature increase from 20°C to 30°C, the lifespan of the batteries is halved.

  • Page 14: Electrical Connections

    Electrical Connections Accessing the FC terminals Danger The following operations must be performed while the FC is disconnected from the utility mains power, switched off and all the input and output power switches on the equipment are open. Before performing connection, open all the input and output power switches and check that the FC is completely isolated from all power sources: battery and AC power line.
